ecshop二次开发
顺便把这几个参数能讲下么:
<!--{foreach from=$hot_goods item=goods name=hot_goods}--> 展开
调用分类下的商品方法:
1.
首先、我们再在/includes/lib_goods.php下增加如下代码:这个代码我加在了最底部:
function index_get_cat_id_goods_best_list($cat_id = '', $num = '')
{
$sql = 'Select g.goods_id, g.cat_id,c.parent_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' .
"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
"promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, goods_img, " .
"g.is_best, g.is_new, g.is_hot, g.is_promote " .
'FROM ' . $GLOBALS['ecs']->table('goods') . ' AS g ' .
'LEFT JOIN ' . $GLOBALS['ecs']->table('category') . ' AS c ON c.cat_id = g.cat_id ' .
"LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
"ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' ".
"Where g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 ".
$sql .= " AND (c.parent_id =" . $cat_id. " OR g.cat_id = " . $cat_id ." OR g.cat_id ". db_create_in(array_unique(array_merge(array($cat_id), array_keys(cat_list($cat_id, 0, false))))) .")";
$sql .= " LIMIT $num";
$res = $GLOBALS['db']->getAll($sql);
$goods = array();
foreach ($res AS $idx => $row)
{
$goods[$idx]['id'] = $row['article_id'];
$goods[$idx]['id'] = $row['goods_id'];
$goods[$idx]['name'] = $row['goods_name'];
$goods[$idx]['brief'] = $row['goods_brief'];
$goods[$idx]['brand_name'] = $row['brand_name'];
$goods[$idx]['goods_style_name'] = add_style($row['goods_name'],$row['goods_name_style']);
$goods[$idx]['short_name'] = $GLOBALS['_CFG']['goods_name_length'] > 0 ?
sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name'];
$goods[$idx]['short_style_name'] = add_style($goods[$idx]['short_name'],$row['goods_name_style']);
$goods[$idx]['market_price'] = price_format($row['market_price']);
$goods[$idx]['shop_price'] = price_format($row['shop_price']);
$goods[$idx]['thumb'] = empty($row['goods_thumb']) ? $GLOBALS['_CFG']['no_picture'] : $row['goods_thumb'];
$goods[$idx]['goods_img'] = empty($row['goods_img']) ? $GLOBALS['_CFG']['no_picture'] : $row['goods_img'];
$goods[$idx]['url'] = build_uri('goods', array('gid' => $row['goods_id']), $row['goods_name']);
}
return $goods;
}
2.
第二、在index.php增加以下代码
$smarty->assign('cat_id16_best_goods', index_get_cat_id_goods_best_list(16,8));
其中16是你调用的分类的id,这个分类可以是一级,也可以是二级。要注意有两个16
8是你要调用的条数。
3.
第三、新增一个.lbi,添加如下代码 :我建立的名字是catec68.lib
<!--{foreach from=$cat_id16_best_goods item=goods}-->
<li>
<div ><img class="b1" src="{$goods.thumb}" width="148" height="148" /></div>
<div><A title={$goods.name|escape:html} href="{$goods.url}" target=_blank>{$goods.short_name|truncate:8:true}</A></div>
<div class="f_delline">市场价:{$goods.market_price}元 </div>
<div class="f_red">无忧康价:{$goods.shop_price}元</div>
<div class="f_orange">售出:{$lang.order_number}件</div>
<div></div>
</li>
<!-- { /foreach }-->
第四、在首页模板index.dwt中,在你想显示的位置加上以下代码:
<!-- #BeginLibraryItem "/library/catec68.lib" --><!-- #EndLibraryItem -->
至于这里面的参数
<!--{foreach from=$hot_goods item=goods name=hot_goods}-->
这个是循环一个数组,hot_goods.是在PHP赋值到前台的数字.item是循环的一个一个对象。
name值一般的可以做一些循环次数的判断
